Problems solved by technology
[0003] The purpose of the present invention is to solve the problem that the upper end of the elevator of the existing corn harvester uses the trash removal roller to cooperate with the blower in the middle of the elevator to discharge the trash. The effect of the blower is not ideal. Blowing to the granary, the device is easily damaged, the labor intensity of the laborers is increased, the cost is increased, the working efficiency of the blower is low, the effect is not obvious, etc., and a corn harvester fan device is provided

The invention discloses a fan device for a corn harvester. The fan device for the corn harvester consists of a power supply device, an air suction device, a crushing device, a monitoring device and an active obstruction eliminating device; the air suction device and the crushing device are respectively and fixedly arranged on the power supply device; the monitoring device is fixedly arranged on the crushing device; the active obstruction eliminating device is fixedly arranged at the lower end of the crushing device. According to the fan device for the corn harvester, negative pressure is generated in an air suction blade rotating fan drum so as to suck impurities and the straw which is brought by a lift conveyer into the crushing device; blades of the crushing device rotate to crush the impurities, such as the straw; the crushed straw is thrown out of the corn harvester through the air suction device; the straw impurities which enter a peeling machine are reduced; the load of the peeling machine is lightened; the peeling efficiency is improved; the service life of a peeling roller is prolonged; the failure rate is reduced; the working conditions of the crushing device is monitored in real time by the monitoring device, so that problems are found and failures are eliminated in time; the increment of the impurities in a granary caused by the problem about wind direction is avoided, and the work efficiency and the quality of the corn harvester can be greatly improved.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fan device for a corn harvester. Background technique [0002] At present, with the development of society and the continuous advancement of agricultural technology, agricultural mechanization has begun to spread rapidly. Corn harvesters are more and more popular with farmers due to their high harvesting efficiency. With the deepening of agricultural modernization, corn harvesters must be It will become one of the important tools of modern agriculture. However, with the high-intensity use of corn harvesters, many problems have also arisen. Due to the vast differences in operating terrain and operating environments in various regions, there are various varieties of corn crops. Influenced by multiple factors such as limitations of experience and working habits, straws and other sundries of different lengths and thicknesses will reach the upper end of the elevator during the ...
